Haha! I worked a decade in retail and always got complaints anytime a set moved. Sometimes the moves made perfect sense, other times they were ridiculous, and 100% of the time they were complained about.
They just did this at my store too! I had seriously just memorized it all, (In fact i still know the old aisle had coffee and tea on aisle 2...photographic mind), but now, i think its aisle 5??
